```C

typedef struct {

    ngx_str_t ed;  //该结构体定义在这里 https://github.com/nginx/nginx/blob/master/src/core/ngx_string.h

} ngx_http_echo_loc_conf_t;

```

HTTP_MODULES="$HTTP_MODULES ngx_http_echo_module"

NGX_ADDON_SRCS="$NGX_ADDON_SRCS $ngx_addon_dir/src/ngx_http_echo_module.c"

```

## make && make install

```shell

 ./configure --prefix=/usr/local/nginx/ --add-module=/root/ngx_dev && make && make install

```

## Successful installation
